Very cute and well loved dog toy.
I have two maltese rescue dogs. One if still a puppy and the other is almost 5 years old. The youngest one is a chewer and goes through toys removing whatever she can as soon as she can. This is a VERY cute toy and comes with the 4 cute bunnies inside. My older dog loves to take the bunnies and cuddle them in her bed. So far the chewer has not been able to take them apart and for that I am very pleased. Very well made, stiched well. I was reluctant at first to purchase because of price, but I believe this is good value for your money.

Each animal has a squeaker so it makes it good for chewing and retrieving. The squeakers dont last long g enough I use it now to stuff other squeakers in. I won’t ut again.

Lots of Fun!
My Toy Cavapoo loves her bunnies. Good size for small dogs. She enjoys pulling each bunny out and tossing around. Bunnies also squeak which is a big plus for her.

Brilliant fun for dog, except for...
I have a 3yo German Shepherd Dog (GSD) and he can be very hard on toys. On days 1 and 2 he had such fun and we laughed at his good times!
Then...Day 3...cue the Jaws Music... While I was away for 10 minutes, he dismantled the ball into tiny pieces! Even so, the ball continued to light up, make sounds and entertain my GSD!!
Coolest dog toy ever!
If you have a heavy chewer....watch out!
Otherwise, I highly recommend!!
